1st Keima Katsuragi - Quanity is it's own quality. Seriously, even with just the goddesses plus Chihiro and Haqua his harem rocks.
2nd Koyomi Araragi - Adult versions of his lolis would put him at number 1
3rd Issei Hyodo - Bonus points because he actually manages to show physical affection to more than one girl without ending up on a boat.

Since no one has mentioned a reverse harem...Shuurei's pack of guys from Saiunkoku Monogatari. (and there are a LOT more).

This actually makes perfect sense considering the setting in a male-dominated, once upon a time and long ago political fantasy in China. And the characters actually have excellent personalities. characterization and brains - including the main female lead! No one here has personality based on how cute or "moe" they are. And there's no unnecessary slapstick violence, no stupid perverted cliches either. Thank the lord...
